8.The apparatus shown in figure consists of four glass columns connected by horizontal sections. The height of two central column B and C are 49 cm. each. The two outer columns A and D are open to the atmosphere. A and C are maintained at a temperature of 950C while the columns B and D are maintained at 50C. The height of the liquid in A and D measured from the base line are 52.8 cm and 51 cm respectively. Determine the coefficient of thermal expansion of the liquid.
